Brazilian President Luiz Inácio Lula da Silva and Mexican President Claudia Sheinbaum held a bilateral phone call on 23 July to deepen economic cooperation as both export-oriented economies brace for new U.S. tariffs. The leaders agreed to start negotiations aimed at broadening their existing trade accord and underscored the need for closer coordination amid what they described as a period of uncertainty in global commerce. Lula and Sheinbaum invited Brazilian Vice President Geraldo Alckmin to lead a delegation of ministers and business executives to Mexico City on 27–28 August. According to official readouts, the talks will focus on expanding trade in pharmaceuticals, agriculture, ethanol, biodiesel, aerospace and other high-value sectors, with the goal of increasing two-way flows and diversifying markets. The outreach follows President Donald Trump’s announcement of import levies of up to 50% on goods from key U.S. partners. The measures include a 50% tariff on Brazilian products and a 30% duty on Mexican imports, scheduled to take effect on 1 August. Both Brasília and Mexico City have said they will pursue alternative markets and coordinated responses while continuing efforts to engage Washington through existing diplomatic channels.
